' Application filed sata 16,1913. Serial No. 742,360.

.- Be'iitknown that I, Kazmma' Jasmom,a-

citizen of the .United tStates, residingv Philadelphia, in thecounty .of-Bh' ladelp-lna f 5 and State of Pennsylvan a, have invented certain new and usefulpI rovements in Wheels, of which the following Isa specification.

My invention relates. to improvements in '10 wheels, and more particularly to an vim- :p'roved construction. and arrangement of tire for the wheel, whereby a circular series of radially movable blocks are supported at the periphery of the wheel and-are cushloned by a pneumatic tube located inside of the blocks and between parallel plates secured to the rim and felly, whereby the tube 15 protected .against puncture, yet elastically sup-' ports the blocks.

A further object isto provide an improved construction of block having a metal reinforcement sustainingthe pressure and wear to a large extent, yet allowing the block to be composed in the main. of rubber, rubber and canvass, fiber, and .anyothe'r material suitable for the purpose.

With these and other objects iii view, the invention consists in certain novel features of construction and combinations and arrangements of parts as.-willbe more fully hereinafter described and pointed out in the claims.

, In the accompanying drawings: Figure 1 is a view 1n slde elevation lllustratlng my improvements. Fig. 2 is' an enlarged frag mentary sectional perspective view illustratingone of the rings designed to hold a sidep te on the rim. Fig. 3 1s a view in elevation of one of the bolts 20.- Flg. 4 1s a fragmentary view in longitudinal section illustrating my improved arrangement of parts. Fi 5 is aview in section on the line 5-5 of Fig. 1, and Fig. 6 is a-perspective view of the metal reinforcement for one of the blocks.

1 represents an ordinary Wheel felly con nected by spokes '2 with theordinary hub 3,

- and while my invention is not limited to any particular style of wheel, here shown in connection with the ordinary automobile wheel in general use,

Around the fell 1, a ring 4is demountably secured by b ocks 5 and this ring A: I shall hereinafter refer to as a rim be-' causeit constitutes the rim around: th f fly e a s r p e neas W111 a.

now explained, The ring at, at both side" edges, is formed with circular flanges 6, and

side plates 7 are secured to these flanges by split rings 8. The side plates 7 are preferably composed of sheet steel. or other suitable material bowed outward intermediate their edges as indicated at 9 located parallel to each other at their outer edges as indicated at 10, andhaving extended bearing surfaces or base portions 11 located against the outer face of rim t, a nd confined by the rings 8. These rings 8 are of general chanheljshape in cross section, except that the. inner of then parallel members are longer heavy tube having an inner inflated tube 17,

but I, of course. do not limit myself to the. inner and outer tube arrangement, but may resort to any form of pneumatic cushioning tube .which is adapted for the purpose.

Around the outer edge of the tube 16, a circular series of. blocks 18 are located and each block is of general keystone shape, with the adjacent ends of the blocks spaced apart,

and all of said blocks provided with radial slots 19 through which bolts 20 project. The

bolts 20 have reduced screw-threaded. ends 21 which project through openings in plates 7, and are secured by nuts 22. The reduced Patentedeliuly as, rare.

ends 21of the bolts provide shoulders 23 against the inner faces. of plate 7, so that the nuts 22 cannot bind the plates against the blocks, but insure a unlformspacing of the plates apart to allow a free movement of the blocks in compressing the cushioning tube as will be understood. Each ,block 18 is composed mainly of rubber, fiber, or any other suitable material or composition which. .is designed for contact with the ground, and

is reinforced by metal plates as indicated in Fig. 6. This metal reinforcemerrt comprises a perforated base plate 24 upon jhich an inverted U-shaped sheet 25 is secured transversely of plate 24 by a metal strap26. This iiro metal reinforcement is located in the mold Qand becomes-embedded in the material of the block, T he plate 24: constitutes the base of the block; and the metel"s'heet'25consti lutes a metal Wallaround the 5101219 to sus.--

i and prevent the lbloc ks frombeing forced between the parallel port-ions 10 of said, plates. In' other wordsfthese tongues limit the outward movement of the blocks ce'ssity' of providing {in entirely new. the,

I In operation, s tlielntheels move over the ground; the several blocks .W'lll press the tube 26 inwardly. If o'neflof, the, blocks should strike a stone or. other. obstruction, it will be moved. inwardly further than the others but this eiitrzi movement will be caif'edfon withoutiinjury to the tire or'the Wheel. If one of the-blocks 'becomes broken or- Worn,

Furthermore; it'will be notedthat the se'v: eral parts may be'readily' taken aphrt, and 'my improvements lend themselves fo nuse in connection with automobiles and other. Vehicles employing tires of this'general type.

Various slightich'aiiges might-"be made in the general storm-and arrangement of-par-ts deperting from my inmambo ve'ntion; and henee I do not limit myself to the precise details set forth, but consider myself at' liberty to make -such changes turd, alterations as fairly fall Within the spirih I end scope. of the appended claims.
